Will Entering Your PIN in Reverse at an ATM Summon the Police?

Posted by

Have you ever received that WhatsApp pass-on that offers a number of useful tips about things you never knew your mobile phone could do? I have, and I got it again just yesterday. One of the tips in there is the one about ATM PIN reversal aka Reverse PIN Panic Code.

Here is what the tip says:

ATM PIN Reversal

If you should ever be forced by a robber to withdraw money from an ATM machine, you can notify the police by entering your PIN # in reverse. For example, if your pin number is 1234, then you would put in 4321. The ATM system recognizes that your PIN number is backwards from the ATM card you placed in the machine. The machine will still give you the money you requested but unknown to the robber, the police will be immediately dispatched to the location. All ATM’s carry this emergency sequencer by law.

This information was recently broadcast by Crime Stoppers. It is, however, seldom used as people just don’t know about it.

ATM Pin number reverse - ATM PIN Reversal

At a cursory glance, it sounds like a great idea. Unfortunately, it is not true. No bank has implemented such a security measure, even though it was recommended to US banks years ago. As a matter of fact, the software to make this work, ATM SafetyPIN software, was even patented by Illinois lawyer Joseph Zingher. However, as said, it was never implemented.

The ATM PIN Reversal Hoax

Since then, this hoax of typing your ATM PIN in reverse when in a forced situation has been passed round and round. The truth is that if you type your ATM PIN in reverse, you will get an error from the ATM and no cash will be dispensed to you.

Also, no police or security agency will be notified. Of course, delay tactics can be helpful in such an emergency situation, so typing in a wrong PIN under that situation may not entirely be a bad idea. But doing so can go this way or that. Typing in a wrong PIN, which is what your PIN in reverse is, might earn you a few slaps and kicks from your abductors.

In Summary

  1. Typing in your ATM PIN in reverse will get you a “wrong PIN” error
  2. Typing your ATM PIN in reverse will not alert the police

This so-called tip, like many others floating around the Web and being passed along through WhatsApp and other digital channels, is an urban legend. It is not seldom used because people don’t know about it; it is seldom used because it is not true and just does not work.

Stay calm. Stay focused. Be good to everyone. If ever this reverse PIN panic code system is implemented on ATMs, your favourite digital super hero, Mister Mobility, will be here to update you. To infinity and beyond! *zooms off into the horizon*


  1. An old schoolmate on our WhatsApp Group passed on this ‘tip’. Without checking, I knew it want likely to be a hoax


    There are too many exceptions to allow this work.

    -What if your PIN is a palindrome (reads the same forwards and backwards – e.g 4224). How do you reverse that?

    -What if your PIN is made up. of the same digits (e. g 7777). What’s the reverse of that?

    Basically, commonsense would dictate that if something like this would be implemented, a unique code would be reserved (like 9999) which is never assigned to a PIN.

    These kind if hoax is even harmless. The ones we should be very careful about are those ‘medical advice’ passed around online by ‘NoName Medical Doctors’.

    A recommendation or advice is only as good as the person behind it.

  2. We should just find a way to implement this technology, things like are not difficult to implement.. There are a lot of information flying everywhere on what’sapp broadcast that are hoax

  3. It still baffles me how we don’t have an operation emergency response line like the famous 911 operated in the US.

    Can we first start that, then make other ideas come to life.

    As said by our “digital super hero😉” this will not work but give an error.

    So it beats the purpose and a hoax.

    I think our security network and approach is still old school.

    Nigeria needs modern day security options.
